That is... what size pipes to use? Is it necessary to run x pipes to equalize? I was planning on using 2 1/2 inch pipes... same as the headers, but I am leaning towards 2 inch pipes now.
Aplication will be a 302 in a 1940 gmc.
I am also interested in how a setup should look... staight out the back, before the rear wheels, after the rear wheels, etc.
Any tips and links would be appreciated. | | |

The exit area is your own taste. I like em coming out the rear with crome tips. If it is a panel you should exit out the sides.

My 302 is a gmc 6 banger. Cool pic! I'm sure it has a nice exhaust note with those glass packs. | | |

I am going to just weld on some ss 2" straight tips so the exhaust comes straight out the back directly under the bumper.
It sounds really nice with glasspacks...not too loud but if you really get on it they bark pretty good.
